Specification of Letters Patent.

Application filed May 4, 1916. Serial No. 95,465.

To all whom it may concern: Be it known that we, FREDERIC EL BAN- FIELD, J r., LOREN W. PENNEY, and ARTHUR D. COLBY, all of Newton, in the county of Middlesex and State of Massachusetts, and all citizens of the United States, have invented new and useful Improvements in Cardin Engines, of which the following is a specl cation.

It has been a practice todivide the fleece coming oif from the doffer into a plurality of slivers each of which passes through the calender-rolls, and is thereafter carried into and coiled in the cans. Where the number of cans to be used is not over four, they may be arranged in a row in front of the card, and in case one or more of the slivers break down it is a simple matter to piece the broken ends without in any way interfering materially with the product of the machine. When eight cans are used, so far as we know the arrangement has always been four at the front end of the card and four immediately in front of them, so that the cans will be arranged two deep in front of the card.

The practical objection to this arrangement is that in the case of any breaking down of the slivers leading to'either of the middle cans in the line nearer the card, it is necessary to remove one or more of the outer cans in order to get at the breakage to piece it up, and this, of course, results in the breakage of the sliver running to the outer can. The distance from either endof the 'row or over the front row is too great to make it practically possible to piece up otherwise.

Our invention relates to an improvement in the arrangement of the cans whereby, in case, for example, eight cans are used, they are arranged in such way that the sliver running to each can be pieced without interfering with the proper operation of the other cans. It involves certain improvements and details of construction which will be referred to below.

Our invention will be understoodby reference to the drawings, in which it is shown in its preferred form in connection with the dofi'er of the card, the other parts of the card being omitted as unnecessary for its proper explanation.

Figure 1 is a side elevation showing the doffer, the cans and the intermediate mechanism.

Fig. 2 is a plan of the mechanism shown in Fig. 1.

Fig. 3 is a verticalsection on line 33 of Fig. 2. I

Fig. 9 is a plan view of the can removed from the coiler.

.A is the dofi'er, B is the doifer comb and C the calender-rolls.

In machines of this type the fleece is taken by the dofi'er'from the cylinder and from the doifer by the dofi'er comb, and then fed through trumpets 0, each sliver being condensed in its own trumpet. Various means are used for dividing the lap into the necessary slivers. In. the present case such a means is indicated at 0 Being old in the art, however, it is not described; nor are the means shown for rotating the dofi'er. The dofler gear a is in mesh with an idler gear b, which in turn is in mesh with an idler b engaging a pinion b on the shaft 6 carrying the lower calender roll C. C is a bar which carries the trumpets c.

This mechanism so far described is in the main wellknown and'requires no further description. From these trumpets 0 the slivers are carried to trumpets'd in the trumpetplate D, or the trumpets al in the trumpet plate D through which and the collar tubes E the slivers are fed to the cans, passing between the calender-rolls L, L located between the trumpets cl and the coiler tubes E. By this means the sliver is sulilciently condensed.

Each trumpet-plate D, D is made in sections, each section having ears D by which it is hinged to hangers D suitably support-' ed. By this means it is possible to expose each coiler tube independently of the other.

Referring to Figs. 3, 4;, 5 and 6, F is the can table base having four can tables or can receptacles F each adapted .to receive a can Gr. Each can table is provided with a downwardly-pro ecting stud 7 which sets into a suitable bearing f in the base, and as also is provided on its under surface with gear teeth P. The gear teeth f are in mesh with a gear f", of which there are two, each meshing with a pinion f on the bottom of a stud 7'', which carries'above the pinion f a gear f meshing with a gear f cut in the lower end of a shaft F Thus when power is applied to each shaft F the cans in each particular group will be rotated all. in the same direction. It will be noted also that in order to bring this about the shaft is off center with relation to the can table gears and also with relation to column H down through which it passes. The groups are alike so that the description of one applies to both.

Power is applied to it as follows: On top of the column H is supported the coilerplate J, up through a suitable bearing in which the shaft F passes. At its upperend and resting on the coiler-plate is a beveled gear F which meshes with a beveled gear F on the shaft F This shaft F passes out horizontally through one of .the standards D* which form the ends of the head and it carries at its outer end outside the head, a gear F in mesh with a gear F on a stud mounted in the said standard 1) and carrying at its outer end a sprocket F. A chain F connects this sprocket with a sprocket F on the end of the shaft 79 which supports the lower calender-roll so that whenever the card is operating, power is applied through the chain F to the shaft F and the can receptacles F this mechanism being duplicated in both groups the cans will all be rotated in the same direction and at a uniform speed.

The coiler-plate also carries four coiler tubes E on which are mounted tube gears E in mesh with gear teeth on the side of the beveled gear F so that the tube gears and consequently the coiler tubes are rotated with the can receptacles F and preferably in the same direction though more rapidly.

In order to feed the slivers properly to the coiler tubes the slivers are led from the trumpets (Z, (Z between calender-rolls L, L mounted just under the trumpet-plates D, I) in the standards D Power is applied to the calender-rolls L by means of gears Z, Z forming a part thereof, one of which meshes with the gear F and the other with an idler F which in turn meshes with the gear F this construction or its. equivalent being necessary in order that the calender-rolls L, L may draw and feed the sliver in the proper direction.

Thus each group of cans is essentially a unit, its various parts cooperating :to draw or drag and condense the sliver. And it will also be apparent that by reason of the fact that the coiler tubes are led out to substantially the periphery of the tube gears, the sliver would be coiled in all the cans alike in a symmetrical way, so that in the next process of treating the sliver the sliver will be drawn from the can without danger of breakage, the manner of coiling appearing in Fig. 9.

These two groups of cans are located as shown in Fig. 2 in front of the card and in such relation to each other that a fairly wide passage B will exist between them, a passage sufliciently wide to allow an operative to pass between the groups and thus piece up at each can without disturbing either of the others. This also makes it possible to withdraw each can as it becomes full without stopping the card or breaking down either of the other slivers.

By reference to the drawings it will be seen that in each group of can mechanisms the coiler plate J, on which are mounted the gears E carrying the eccentrically arranged coiler tubes E, is supported from the can table base F by a centrally arranged hollow column. through which a shaft F from which the rotating can tables F are driven, passes eccentrieally. By thus supporting the coiler plate J on the substantially central hollow column H unobstructed access is afforded to the cans G, so that said cans can be conveniently placed on and removed from their rotating tables or receptacles F and the said rotating can tables or receptacles may all be properly driven from the shaft F WVhat we claim as our invention is:
